Applications of sapphire product in Medical
· Sapphire is used in surgical systems for laser transmission and in contact with bodily fluids.
Endoscope lenses - sapphire is often used in endoscope lenses due to its durability in contact with tissues and in sterilisation environments such as autoclaving
· Sapphire knives - with a sapphire knife, thinner sections are possible. The near perfect cutting edge of this knife / blade gives distortion-free sections down to 10 microns thick.
· Surgical tips - sapphire is used in contact tips for various surgical laser applications
